Make the following improvements to the self-enrolment wizard.

(a) Validation failures at any stage in the running of the self-enrolment wizard generate a message directing the end user back to the very first wizard page. Address this by rewriting the wizard as a single script solution.

(b) Implement the self-enrolment wizard using sessions rather than hidden form controls to maintain application state. Again, make this a single script solution.
